SIGNALlNG APPARATUS FOR VESSELS.

SPECIFIGATION forming part of Letters Patent No. 647,560, dated April17, 1900.

Application filed December 14, 1899. Serial No. 740.305. (No model.)

To all whom it mf/0 7] concern:

Beit known that l, OSCAR E. EATON,a citizen of the United States,residing in Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Signaling Apparatusfor Vessels, of which the following is a specification.

This invention relates to that style of signaling apparatus for use onboard ship oommonly termed marine mechanical telegraphs, and constructedto enable a signal to be transmitted from the bridge or pilot-house tothe engineers room.

The invention or improvement consists in the novel construction andarrangement of parts whereby the signal is transmitted to the engineersroom and returned therefrom, and the attention of the engineer is calledto said signal by a peculiarly-arranged striking apparatus, all as fullydescribed below, and illustrated in the accompanying drawings, in which-Figure lis a View showing the two portions of the apparatus-that is, theportion located on the bridge and that located in the engineers room-infront elevation, said portions being divided by a deck-floor in section.Fig. 2 is a cross-vertical section taken through the portion in theengineers room. Fig. 3 is a section taken on line 3, Fig. 2, a portionbeing represented as broken out. Fig. l is a rear elevation of theportion shown in Figs. 2 and 3 with the gong removed. Fig. 5 is asection taken on line 5, Fig. 2. Fig. 0 is a diagrammatic View of thecontrivance.

Similar letters of reference indicate corresponding parts.

a represents the deck of a vessel, and a an upright wall in theengineers room. The portion of the apparatus located in the engineroomcomprisesa supporting-bracket b, integral with the rear plate A, inwhich the shaft or stud c has its bearings. Keyed to this stud (See Fig.2) is the grooved wheel B.

C represents the front plate or dial, provided with the usual words orcharacters,snch as full, slow, dsc., said plate being connected with therear plate A by the portion D, whereby the whole constitutes a case. Be-

tween the rear wheel B and the dial C is a grooved wheel E, whose hub E'is loose on the stud c and extends through the dial. A pointer F issecured to this hub E' and extends radially over or in front of the dialfor a short distance, as shown. The stud c has rigidly secured to it atits rear end a pointer, which consists of the arm H, bent forward at Hand with its front end provided with the hand H, extending over the edgeof the dial, as shown.

The construction of the sending portion of the apparatus is the same asthat of the receiving portion above described, such portion comprising aoase, the dial d, and the grooved wheels e f, the former fast on thestud e and the latter loose thereon and free to rotate behind the dial.The stud c' is provided with a pointer g, exactly like the pointer H HIl, and the hub of the front wheelf is provided with the pointer g. Thearms or pointers ll', H, and g are provided with suitableoperating-handles h and g, respectively. An endless chain or band Kconnects the rear wheel B in the receiving portion with the front wheelf in the sending portion, and a similar endless chain or band K connectsthe front wheel E in the receiving portion with the rear wheel e in thesending portion, said chains crossing each other and extending upthrough the open structure b', over and under the rolls Z, through thehollow post I, which supports the sending portion, and over the rolls m.

L, Figs. 2 and 5, represents a verticallyarranged gong supported by thehorizontal post L', which is integral with the rear plate A. This plateis provided near its upper end with an integral bearing A for the shaftM, rigid o the forward end of which is a trip N, Figs. 2 and 3, andrigid on the rear end of which is a lever N', Figs. l and 5, whose outerend is pivotally connected-with a link P, pivoted at its opposite end tothe bell-crank R, fast on the stud R,which is supported by the rearplate A, the trip N overlapping the front surface of the wheel E, andthe parts N, P, R, and R', being behind the rear plate A and between itand the inner surface of the gong. A spring S connects one end of thebell-crank R with the post L', and a hammer U has its end rigid orintegral with the stud R.

The front face of the wheel E is provided near its periphery with anumber of horizontally-extending studs V, corresponding with. the spaceson the dial.

IOO

In practical operation when a signal is to be given from the bridge thehandle g is moved down until the pointer g overlaps the word whichindicates the desired signal, as shown in dotted lines in Fig. l. Thisrotates the rear wheel e in the sending portion, and by means of thechain K communicates corresponding rotation to the front wheel E in thereceiving portion. The rotation of the wheel E causes a number of thestuds V, corresponding to the desired signal, to act on the trip N thesame number of times, each stud lifting the trip and swinging the leverN', which by means of the link P operates the crank R and swings thehammer U against the power of the spring S, said spring when the trip isreleased causing the hammer to strike the rim of the gong. Thus if thehandle g is swung into the position indicated by dotted lines in Fig. lthe gong is rung three times, calling the attention of the engineer tothe fact that a signal is given and notifying him what the signal is. Atthe same time the hub E of the wheel E rotates to move the pointer Fover the same signal which is indicated by the dotted lines in Fig. l.The engineer is thus provided with both audible and visual information,not only that a signal has been given,but exactly what that signal is.The engineer acknowledges the signal by moving the pointer H" over thespace indicated by the pointer F, so that said pointers face each other,with the effect of rotating the rear wheel A in the receiving portionand transmitting similar movement to the front wheel f in the sendingportion by means of the chain K, said wheel f moving the pointer g overthe signal given on the dial d, as indicated by dotted lines in Fig. l.Thus the sender knows that his signal has been received by the engineerand knows that the engineer understands it.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

The herein-described improved signaling apparatus for vessels,consisting of the receiving apparatus comprising the front plate or dialC suitably inscribed; the rear plate A; the portion D connecting saidfront and rear plates; the stud c supported by the plate C; the groovedwheel E provided with the hub E loose on said stud; the wheel B keyed tosaid stud; pointers F and H extending from the hub E' and stud crespectively; a similarly-constructed sending apparatus; the openstructure h/ extending from and connecting with the interior of the caseof the receiving apparatus; the endless chain or band K connecting therear wheel in the receiving portion with the front wheel of the sendingportion; the endless chain `or band K crossing the chain K andconnecting the front wheel in the receiving portion with the rear wheelin the sending portion; the studs V extending horizontally from thefront wheel E in the receiving portion; the horizontal shaft M extendingfrom a point in front of the wheel E to a point at the rear of the caselof the receiving apparatus; a trip on the forward end of said shaft andadapted to be engaged by the studs V; the gong supported by said case atthe rear of the rear plate; the lever N rigidly secured to the rear endof the shaft M; the bell-crank R supported by the case; a linkconnecting said lever N and bellcrank; a spring connecting thebell-crank with the case; the stud R; and a hammer extending from thestud,- substantially as described.
